Thread: server permissions for sql copy

server permissions for sql copy

From

Good morning,

I'm running PostgreSQL 7.0.2 on Caldera eDesktop 2.4.
when I try to use the SQL COPY command in psql, I get
an error message informing me that the backend could
not open the file for reading.  I think the error
number was 13 - Permission denied.  I changed the
permissions of the directory and file to
world-readable; but I still get the same error
message.

Does anyone have any suggestions as to what I should
try next?

Thanks,

Andrew Gould

What about the directories above the one containing the file?

Also, don't forget that the critical permission for a directory
is execute (= "allow lookup of entries"), not read (= "make a
directory listing").  You probably want permissions rwxr-xr-x
or rwxrwxr-x on directories that need to be publicly readable.

Keep in mind it's the *server* process (user postgres), trying to get
to the file, not the psql user (probably you). Is the file in *your*
home directory?

You'll need to chmod a+rx this directory, and all directories above
this directory.

On our server, we've created a directory for pgsql copying and
dumping that is rwx for postgres and our DBAs.

Yup, that was the problem.  COPY works fine now.

Thanks for yet another lesson.
